- * We store a bitfield in the hash table, with five possible values total.

- *
- * The FOUND_BIT is needed to differentiate the value of DISABLED from
- * the value returned by HashTableLookup() when it can't find the given key.
- *
- * The KNOWN_SEVERITY bit is a bit complicated:
- *
- * A client may call Control() with an array of IDs, then call Control()
- * on all message IDs of a certain severity, then Insert() one of the
- * previously specified IDs, giving us a known severity level, then call
- * Control() on all message IDs of a certain severity level again.
- *
- * After the first call, those IDs will have a FOUND_BIT, but will not
- * exist in any severity-specific list, so the second call will not
- * impact them. This is undesirable but unavoidable given the API:
- * The only entrypoint that gives a severity for a client-defined ID
- * is the Insert() call.
- *
- * For the sake of Control(), we want to maintain the invariant
- * that an ID will either appear in none of the three severity lists,
- * or appear once, to minimize pointless duplication and potential surprises.
- *
- * Because Insert() is the only place that will learn an ID's severity,
- * it should insert an ID into the appropriate list, but only if the ID
- * doesn't exist in it or any other list yet. Because searching all three
- * lists at O(n) is needlessly expensive, we store KNOWN_SEVERITY.
